Abstract
Topological insulators (TIs) such as single-crystalline BiTe exhibit remarkable metallic surface states with a Dirac cone structure, offering significant potential for next-generation technologies. However, their practical application remains limited, in part due to insufficient control over the fine details of their electronic structure. This paper investigates how annealing influences the fundamental properties of BiTe. High-sensitivity surface characterization techniques – including scanning tunneling microscopy and spectroscopy (STM/STS), along with electronic transport and magnetotransport measurements performed below 1 K – were employed to probe these effects, enabling the detection of Shubnikov–de Haas quantum oscillations. The experimental results were further compared with density functional theory (DFT) calculations. A key finding of the study is how the surface electronic states of BiTe are affected by thermal treatment. At elevated annealing temperatures, a new phase emerges that partially covers the surface, displaying a locally distinct electronic structure compared to the pristine material. Notably, despite the presence of this phase over large surface areas, the overall conductivity of the sample remains intact.
